# HALOWERK Land Dossiers – Wind Farm Terrain Screening

> HALOWERK Land Dossiers – Wind Farm Terrain Screening is a paid API for AI agents from landdossier.halowerk.com, paid per call via x402, $0.012/call, status unknown (last checked 2026-09-15).

Returns a balanced evidence dossier for wind farm site suitability using six disclosed terrain measurements and a deterministic score for a given European location and radius.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability halowerk-land-dossiers-wind-farm-terrain-screening-488fc9e7 -d '<json body>'
```

Example prompt: Can you run a wind farm terrain screen on the HALOWERK land dossier for coordinates 53.4°N, 8.1°E with a 500-metre radius and show me the balanced evidence score and the six terrain measurements?

## When to prefer this

Use this endpoint when you need a fast, deterministic, cost-effective pre-feasibility screen for wind farm terrain suitability at a specific European location. Prefer it over general GIS queries when you need a structured six-metric evidence dossier with a single comparable score, especially for portfolio screening across multiple candidate sites. Not a substitute for full environmental impact assessments, legal permitting, or valuations.

## Known failure modes

- Coordinates outside European coverage (lat 34–72.5°N, lon -31.5–40.5°E) will return a coverage error
- Radius outside allowed range (50–2000 m) will return a validation error
- Payment failure via x402 protocol will prevent dossier generation
- Missing required latitude or longitude fields will return a schema validation error

## How this service works

Decision-support dossier for wind farm terrain screening using six disclosed measurements and a deterministic balanced evidence score. It is screening evidence, not a permit, valuation or legal determination.

## Output

A decision-support dossier containing six disclosed terrain measurements relevant to wind farm siting, plus a deterministic balanced evidence score aggregating those measurements. The response is screening evidence only and does not constitute a permit, valuation, or legal determination.
